Using insurance claim data, we empirically offer a more nuanced understanding of the impact of bundled payment policy on hospital operations and provide new evidence from China. Our evidence suggests that transitioning from fee-for-service to bundled payment reimbursement resulted in declines in treatment costs and length of stay. Along with that decline, there was an increase in planned revisits to outpatient clinics, which indicates a shift of care from the inpatient to the outpatient setting, as well as a rise in unplanned revisits, indicating a decline in service quality. The increase in readmission rate to inpatient wards is very small and not statistically significant. In addition, we discuss the design and implementation of bundled payment. Our results imply that careful bundle design is vital to encouraging providers to implement the new program without sacrificing quality.

An Integrated Carsharing System with Dual Service Types","authors":"Hua Ke, Yutong Mo","doi":"10.1287/serv.2022.0312","DOIUrl":"https://doi.org/10.1287/serv.2022.0312","url":null,"abstract":"A specific service type is applied by most one-way carsharing operators, either station-based or free-floating, which depends on whether users are required to pick up and return vehicles in fixed parking lots. However, both of them have inherent limitations. The station-based carsharing system encounters the weakness of low parking-space utilization, whereas the free-floating system needs to face high parking and relocation costs. To overcome the limitations of single-type carsharing systems, this paper proposes an integrated system to apply the two types in different parts of the service area. A mixed-integer linear-programming model is established to maximize the operator profit, considering both strategic decisions of service type and operational decisions of relocation and trip selection. Despite the fact that the model can be solved by the CPLEX solver, it is limited by excessive memory usage and too long solving time in large-scale cases. To enhance the solving feasibility of the proposed model, a heuristic algorithm is proposed to effectively iterate feasible strategic options and solve the operational subproblem. The numerical results of the case study show that the proposed algorithm can achieve comparable objectives with the CPLEX solver in a much shorter computational time. Through system comparison, the integrated system achieves a larger profit and higher demand-fulfillment rate, compared with the single station-based or free-floating system.

Therefore, we introduce the instant delivery problem (IDP) to replicate and examine two widely adopted strategies in the rapid delivery market: the personal shopper system (PSS) and the inventory owned delivery (IOD) system. In the PSS, couriers visit affiliated brick-and-mortar stores in the delivery area to pick up and purchase ordered products and then deliver them to customers. In the IOD system, couriers collect products from a single distribution center, or so-called dark store, in which the platform manages the inventory. Even though a PSS strategy is asset light because of the utilization of existing retailers in the area, maintaining a good level of on-time instant deliveries with the PSS is more complex than with IOD. This is because the PSS requires deciding which store to purchase ordered goods from, and picking and shopping at stores needs to be considered in the real-time decision process. We propose a tailored rolling horizon framework that utilizes column generation to browse updated delivery plans for arriving customer orders. Computational studies both in real life–inspired settings and in case studies on selected urban areas show that the PSS is a highly competitive strategy compared with IOD, particularly when dealing with small-sized customer orders. We observe that the performance of the PSS is robust when varying the delivery service time frame. The case studies also suggest that the PSS becomes even more competitive in areas where the retail store density is high. History: Special Issue—Innovation in Transportation-Enabled Urban Services.

With technologies (e.g., electronic shelf labels) enabling retailers to change prices easily within each day, should supermarkets use peak-hour pricing? To examine this question formally, we introduce a stylized duopoly model in the presence of “negative externality,” where firms compete for congestion-averse customers. We characterize how customers endogenously segment themselves regarding when and where to shop, and then use the equilibrium outcomes to examine whether the firms should implement peak-hour pricing for varying types of customer flexibility and competitive asymmetry. Our analysis shows that, if customers are not flexible in their store choice, then both firms would always use peak-hour pricing. However, if store choice flexibility is present, then firms’ decisions depend on the competitive asymmetry as follows. If one firm has a clear competitive advantage (in terms of value or price) over the other firm, then the dominant firm will use peak-hour pricing, whereas the other firm will not. Otherwise, both firms will use peak-hour pricing if they engage in symmetric competition (in terms of similar value and price), or neither firm will use it if they engage in differentiated competition (high value versus low cost). Through our analysis of different extensions, we find that a firm’s ability to set its regular price would dampen the effect of peak-period pricing. Also, we obtain consistent results when there is heterogeneity in customer valuation and customer congestion aversion level.","PeriodicalId":46249,"journal":{"name":"Service Science","volume":"40 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81383489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study fills this gap. With a focus on retail brand experience, this study demonstrates that cross-channel integration impacts customer experience and further results in changes in perception and behavioral intention. A conceptual model that illustrates the customers’ psychological mechanism responding to cross-channel integration was developed. To test the model, a scenario-based online experiment was conducted. The results show that perceived channel integration impacts retail brand experience, which in turn impacts perceived service convenience, satisfaction, and patronage intention. Creating a better experience is a key challenge for retailers to ensure customer satisfaction and brand loyalty. Our results show that cross-channel integration services can play a pivotal role in the shaping of retail brand experience in today’s competitive retail environment that continuously evolves, owing to digital technology. The findings of this study add valuable new knowledge to the growing omnichannel retailing literature and provide practical insights to develop omnichannel retail services.","PeriodicalId":46249,"journal":{"name":"Service Science","volume":"62 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87503137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, many companies are trying to launch new digital services on the market to realize this potential. Prior research concludes that the success of such services depends crucially on whether a consumer adopts or rejects them. Hence, by using the methodology of a systematic literature review, this paper identifies key factors that drive a consumer to adopt digital services. As a result of a subsequent classification, the present work distinguishes among three main categories. First are consumer-specific factors relating to individual predispositions, demographics, and awareness factors that can be attributed to the consumer. Second are situation-specific factors, representing the smallest category found, concerning the service environment, the context of service delivery, and situations in which consumers may find themselves before or during the use of digital services. Third are service-specific factors that are mainly determined by individual characteristics and features of these services, such as ease of use, usability, compatibility, and enjoyment. Hence, this study provides a comprehensive overview of determinants affecting consumer’s adoption behavior and suggests several opportunities for future research. Whereas the rich set of identified factors serves as a foundation, it further proposes to what responsible service executives should pay particular attention in order to succeed with digital services.","PeriodicalId":46249,"journal":{"name":"Service Science","volume":"85 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90355387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work studies a problem of fully response-adaptive Bayesian design of phase II dose-finding clinical trials with patient information, where the decision maker seeks to identify the right dose for each patient type (often defined as an effective target dose for each group of patients) by minimizing the expected (over patient types) variance of the right dose. We formulate this problem by a stochastic dynamic program and exploit a few properties of this class of learning problems. Because the optimal solution is intractable, we propose an approximate policy by an adaptation of a one-step look-ahead framework. We show the optimality of the proposed policy for a setting with homogeneous patients and two doses and find its asymptotic rate of sampling. We adapt a number of commonly applied allocation policies in dose-finding clinical trials, such as posterior adaptive sampling, and test their performance against our proposed policy via extensive simulations with synthetic and real data. Our numerical analyses provide insights regarding the connection between the structure of the dose-response curve for each patient type and the performance of allocation policies. This paper provides a practical framework for the Food and Drug Administration and pharmaceutical companies to transition from the current phase II procedures to the era of personalized dose-finding clinical trials.","PeriodicalId":46249,"journal":{"name":"Service Science","volume":"31 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2022-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74545962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
